Most parts of the Philippines will continue to experience generally fair weather on Saturday, although scattered rains and thunderstorms are expected over parts of northern Luzon and Mindanao due to the frontal system and the intertropical convergence zone (ITCZ).
Weather Systems Affecting the Country
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that the frontal system is affecting extreme northern Luzon, bringing cloudy skies with scattered rains and thunderstorms over Batanes and the Babuyan Islands. Moderate to at times heavy rains may trigger flash floods or landslides in these areas.
Meanwhile, the ITCZ is affecting southern Mindanao, bringing cloudy skies with scattered rains and thunderstorms over Zamboanga Peninsula, Sultan Kudarat, Sarangani, Lanao del Sur, Maguindanao del Norte, Basilan, and Tawi-Tawi. PAGASA warned residents in these areas of possible flooding and landslides during moderate to heavy downpours.
Metro Manila and the Rest of the Country
Metro Manila and the rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms caused by localized thunderstorms. The weather bureau said severe thunderstorms may still trigger flash floods or landslides in vulnerable areas.
PAGASA noted that no low-pressure area (LPA) is being monitored, after the previous weather disturbance formerly identified as Tropical Storm Caloy dissipated.
Wind and Sea Conditions
Moderate winds and moderate coastal waters will prevail over northern Luzon, while the rest of Luzon, Visayas, and Mindanao will experience light to moderate winds with slight to moderate seas.
